Although that sounds easy, it can be counter-intuitive. The problem is the precision of coordinates. For example, in our project ( http://dobrotvor.com/ ) we bumped into this due to the fact that the precision of geo coordinates incapsulates the zoom value of Google Maps points. It's not right just to compare (X1 == X2) AND (Y1 == Y2) since the results can be wrong in many cases.

To make it work right, it's better to use special function (couldn't find anything better built-in):
